Mark 2:20 The days will come when the bridegroom is taken from you ...
Mark 8:31 And he began to teach them that the Son of man must suffer many things, and be rejected by the elders and the chief priests and the scribes, and be killed, and after three days rise again. 32 And he said this plainly. ...
Mark 14:35 And going a little farther, he fell on the ground and prayed that, if it were possible, the hour might pass from him. 36 And he said, "Abba, Father, all things are possible to thee; remove this cup from me; yet not what I will, but what thou wilt."
Or consider Luke's Last Supper scene:
Luke 22:21 But behold the hand of him who betrays me is with me on the table.22 For the Son of man goes as it has been determined; but woe to that man by whom he is betrayed!"
That is, Jesus knows that he'll be "betrayed" but, he says, his fate has already been determined. So he doesn't catch the midnight donkey-train to Galilee ─ he stays where he is, where he can be found, so that things can go "as it has been determined".
And those verses are just a sample. In all four gospels he says he's on a suicide mission, he makes sure it ends in his death, and he succeeds.
Where do you say it says anything different?
(Incidentally, at no time does he explain why it's necessary for him to die, or what his death can achieve that God couldn't achieve just with one snap of those omnipotent fingers. Nor have I ever figured out a sensible answer to that question.)
